Help with shared memory usage

Re: Does ngx_pool_t survives reload ?

As far as I know, ngx_pool_t are created on process memory area, so, after a reload the new process has a new memory area and do not have access to the old. You can recompile the regex on your module startup, at init worker hook. On Wed, May 7, 2014 at 6:16 AM, MAGNIEN, Thierry

larger than a page size are possible from the pool. While this isn't a problem for nginx itself, it is known to be bad for various 3rd party modules. Fix is to merge adjacent blocks of free pages in the ngx_slab_free_pages() function. Prodded by Wandenberg Peixoto and Yichun Zhang. diff

Should ngx_atoi and ngx_atof functions change their signature?!

Hi, today I realized a possible problem on the ngx_atoi and ngx_atof functions (may be on all ngx_ato* functions). There is no way to distinguish between an error and a valid "-1" string. For instance, ngx_str_t some_string = ngx_string("-1"); ngx_int_t x = ngx_atoi(some_string.data,
